# broken-link-check

> broken-link-check is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Extracts all links from a given webpage and HEAD-requests up to 30 of them (external links first), reporting HTTP status per link and listing broken (4xx/5xx/unreachable) ones.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability broken-link-check-4d1aa031
```

Example prompt: Can you check all the links on https://example.com/blog/post-1 and tell me which ones are broken or returning errors?

## When to prefer this

Choose this endpoint when you need lightweight, no-crawler content QA — specifically to identify broken outbound or internal links on a single page without running a full site crawl. It's ideal for pre-publish checks, periodic health monitoring of key pages, or validating partner/resource pages. Prefer alternatives if you need full-site recursive crawling or deep content analysis beyond link status.

## Known failure modes

- Target page is unreachable or returns non-200, so no links can be extracted
- Page has no extractable links (e.g. JavaScript-rendered SPA without SSR)
- All 30 HEAD requests time out due to slow or blocked servers
- Some links block HEAD requests, causing false positives
- Rate limiting or firewall blocks the checker's requests to target domains

## How this service works

Broken link check: extracts the links on a page and HEAD-requests up to 30 of them (external first), reporting status per link and the list of broken (4xx/5xx/unreachable) ones. Content QA without a crawler. $0.01 per page.

## Output

A per-link status report showing the HTTP response code (or unreachable error) for each link found on the page (up to 30, external links prioritized), plus a summarized list of all broken links (those returning 4xx, 5xx, or that were unreachable).
